Application filed March 20, .1903. Serial No. 148,778.

T0 all whom, zit may concern:

Be it known that I, JAMES M. SULLIVAN, a citizen of the United States, residing at Chicago, county of Cook, State of Illinois, have .invented a certain new and useful Improvement in Coking-Ovens; and I declare the followmg to be a full, clear, and exact description of the invention, such as will enable others .skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates, in general, to cokingovens, and more particularly to ovens especially designed for coling bituminous coals,

hitherto classified as non-colzing.

The primary object of my invention is to provide an apparatus for eliminating from bituminous, semibituminous,and lignite coals, such as are ordinarily regarded as non-coking, the volatile ingredients whichdo not contribute to the value of the coal as a fuel without consuming the original fixed carbon of the coal, thereby converting the coal into a smokeless fuel possessing a maxium capacity for producing heat.

A further object of my invention is to provide an apparatus for coking coal in which the heat resulting from coal in an advanced stage of colzing is rendered available for promoting the process of coking coal in an initial stage of coling.

My invention has for a final object the production of eoling-ovens which will be simple in construction, comparatively inexpensive to build, and economical and eflieient in operation.

The embodiment of my invention herein disclosed consists, generally described, in two .series of ovens, the adjoining ovens in each series being separated by party-walls, through which damper-controlled passages extend, and a flue extending between the two series of ovens having damper-controlled passages communieating with the individual ovens of each series.

My invention further consists in a combined coking and steam-generating plant comprising a battery of cooking-ovens, arranged in parallel series, boilers supported between the domes of adjacent ovens, and a steam-drum connected to the several boilers and supported above a flue extending between and communieating with the individual ovens in the series.

My invention will be more fully described hereinafter with reference to the accompanying drawings, in which the same is illustrated as embodied in aconvenientand practical form, and in whichM Figure l is a front elevational View; Fig. 2, a sectional plan view taken on line 2 2, Fig. l; Fig. 3, a longitudinal sectional elevation taken on line 3 3, Fig. 9.; and Fig. A, a transverse sectional elevation taken on line A A, Fig. 2.

The same reference characters are used to designate the same parts in the several figures of the drawings.

The plurality of ovens are shown as of the usual beehive type, and are arranged in two parallel series, one series comprising the ovens A', A3.y A5, and A7, while the other series comprises the ovens A2, Ai, A6, and AS. The individual ovens are provided with the usual doors, through which the coal when coked is withdrawn, such doors being designated at e a2- as, &c. A trunnel hole (t is provided through the dome of each oven. A flue B extends between the series of ovens and is inclosed by the inner-end walls of the ovens in the two series and by an arched top `71. Any suitable material may be used in the construction of the walls of the ovens capable of withstanding the heat incident to the process of manufacturing coke from bituminous coal, A passage-way is provided between the ue B and each individual oven in the two series, such passages beingindicated as B B2B, &c. Dampers 7) L2 3, Sac., are provided for controlling the openings through the passages B', &c., and are actuated by any suitable means--such, for instance, as rods extending upwardly above the ovens, as shown in Fig. A. rIhe adjoining' ovens of each series are separated by party-walls, through which extend passages, such passages being indicated by reference characters C/ (ji C, Sac. These passages are controlled by dampers e' C 03,

85e., preferably constructed oi fire-brick and provided with rods e, extending to the eX- l terior of the walls ol. the ovens, where they may be readily actuated.

ln order to establish a draft through the ilue ,l a i'an D or similar device is placed in comn'iunication with the Aflue by the short conduit (l. rlhe ian l) may be mounted in any suitable niainierwsuch. for instance.y as upon a shaft fil', which may bc rotated by a wheel D', to which rotary motion maybe communicated by suitable power connections.

ln order that the heat generated during the coliingl process may be utilized, il provide a series oi boiicrs El E, dac., which are supported between the arched denies on adjacent ovens. These boilers are located within cylinders c, formed oi' lire-brick and extending' from the outside walls otl each series ot' ovens to points adjacent to the wall 7) at the top ol the ilue B. A steam-drum F is supported longit (finally above the ilue B and is connectn ed by pipes f with the several boilers. The stean'i may be delivered from the drum i? to any points where it is desired to use the same tor heating or power purposes.

,lfhe 'iloors oi the several ovens are preferably covered by lire-brick supported upon the ground (i at a level with the doors a u, a, ic. The separate boilers are preferal covered with loam or other material to prevent the radiation ot heat therefrom.

The operation oi' my invention is as follows: il-ritornato ovens in each series are charged simultaneously, and the coling process ot the coal initiated tlierein. lf, i'or instance, the ovens A/ and A5 in one series and the ovens A? and A in the other series are simultaneously charged, the dampers controlling the passages in the side walls are closed and those communicating with the line li are open,so that ad rat't maybe established from the iiue through the trunnel-lioles (i in each of the ovens so charged. After the process oi coking in the ovens first charged has progressed a predetermined degree the heat generated is utilized to promote the coldng in the intermediate ovens A3 and A; Vin one series and A and AS in the other series which have been charged ready i'or the initial stage oi" coliing. .lin order to thus utiiizc the heat 'troni the ovens where the coking process is in an advanced stage to cX- pedite the initial coliing in the adjacent ovens, the dainpers 7) and b are closed, as well as the trunnel-holes through the domes ol the ovens A', A, A?, and A, while the dampers i, '/f, if, and /f remain open and the dampers U C C5 and C2, Cl, and C are opened. This arrangement ot' the dampers results in drafts being established Afrom the [ine B through the danipers o' and thence through the ovens A and thence through the passages C and C3 into the oven il. and through the trunnelhole in the dome thereof, thereby expediting the coliing in the oven A. ln a similar manner a draft is established from the i'iue R through the ovens A and A" into the oven A* and through the trunnel-hole therein.

lt is obvious that the system is capable or' almost indelinite extension, it being merely necessary to first charge alternate ovens in each series and subsequently establish drafts through them into the adjoining ovens, in which the coliing process is at an initial stage. The heat resulting from the coking process in the several ovens is communicated to the boilers supported between the curved domes on the ovens, and the steam which is generated therein passes to the common steam-drum il, from which it may be delivered to any desired points,

l/Vhile the use oi' ovens embodying' my invention will not eliminate all extraneous matters-sueh as sulfur, ash, `zc.-inherentin certain grades ot' bituminous coal, and conso quently is-incapable of producing' metallurgical eolie from such grades oi' coal, neverthelcss a domestic coke may be readily produced constituting' an ideal smokeless deniestic fuel. Prior to introducing some grades elE bituminous coal into the ovens better results may be eliected by washing the coal by any well-known method, thereby removing extraneous matter. When higher grades oi'l bituminous coal., or coals Jfrom which the eX- traneous matters can be washed, are introduced in the ovens, it is possible by merely prolonging the period or burning' to malte a metallurgical colte equal in eiliciency to colic made in the ordinary beehive-oven iroi'n iiigli-grade coking-coals.

From the foregoing description it will be observed that I have invented an improved coling-oven in which the heat resulting Vtrom the coling of coal when the process is in an advanced stage is rendered available for promoting' the colting of coal in other ovens in which the nroccss is in an initial stage.

lVhile i have described more or precisely the details oi construction, ido not wish to be understood as limiting myself t iereto, as i contemplate changes in Jform, the proportion oil parts, and the substitution of equivalents as circumstances may suggest or render expedient without departing from the spirit of my invention.

Having now fully described my invention, what l claim new, and desire to secure by Letters Patent, isvd 1. in an apparatus Afor colting coal, the combination with a plurality oi' ovens arranged in parallel series.y oit' party-walls separating adjoining' ovens through which passages extend, a flue extending between the series of ovens having passages communicating with the individual ovens in each series., and dampers controlling' sad passages in the walls and in the ilue whereby alternate ovens in each series may communicate with said ilue through the adjoining' ovens.
